> Minify colors in your CSS files with PostCSS.

## Install

With [npm](https://npmjs.org/package/postcss-colormin) do:

```
npm install postcss-colormin --save
```


## Example

```js
var postcss = require('postcss')
var colormin = require('postcss-colormin');

var css = 'h1 {color: rgba(255, 0, 0, 1)}';
console.log(postcss(colormin()).process(css).css);

// => 'h1 {color:red}'
```

For more examples see the [tests](src/__tests__/index.js).


## API

### colormin([options])

#### options

##### legacy

Type: `boolean`  
Default: `false`

Set this to `true` to enable IE < 10 compatibility; the browser chokes on the
`transparent` keyword, so in this mode the conversion from `rgba(0,0,0,0)`
is turned off.
